For example,signed int,unsigned int,short int,long int, etc. are all valid data types in the C language. long long num = 123456789987654321; // we cannot store a value this big value using int data type. Now let's see the range for different data types formed as a result of the 5...
Type Conversions Programming Tips See also Holds unsigned 16-bit (2-byte) code points ranging in value from 0 through 65535. Eachcode point, or character code, represents a single Unicode character. Remarks Use theChardata type when you need to hold only a single character and do not need ...
